[Media with yeast RNA for isolating Shigella flexneri from feces]. 1978

M V Zemskov, and Iu G Pritulina

The authors demonstrated a considerable, in comparison with the control, increase of the biomass of Sh. flexneri causative agent, when growing in meat-peptone broth with 1-4 mg of NaRNA, and of the number of colonies in the feces of the patients and of healthy persons artificially contaminated with Sh. flexneri when inoculated in Ploskirev's agar or Endo medium with 4 mg/ml of NaRNA. Using media with NaRNA for laboratory diagnosis of dysentery is recommended.

UI	MeSH Term	Description	Entries
D003470	Culture Media	Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.	Media, Culture
D005243	Feces	Excrement from the INTESTINES, containing unabsorbed solids, waste products, secretions, and BACTERIA of the DIGESTIVE SYSTEM.
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D012313	RNA	A polynucleotide consisting essentially of chains with a repeating backbone of phosphate and ribose units to which nitrogenous bases are attached. RNA is unique among biological macromolecules in that it can encode genetic information, serve as an abundant structural component of cells, and also possesses catalytic activity.
